Shield tunneling interval risk management system based on construction of shield tunneling machine

Abstract

The invention belongs to the technical field of construction application of subway rails, and particularly discloses a shield tunneling interval risk management system based on construction of a shield tunneling machine. The system comprises a shield tunneling construction real-time monitoring unit, a database connection reading module, a data processing module, a graph output module and a graph operation module. The database connection reading module, the data processing module, the graph output module and the graph operation module are connected with the shield tunneling construction real-time monitoring unit. The shield tunneling interval risk management system based on construction of the shield tunneling machine has the beneficial effects that 1, the technology is applied to development of an information system, so that the flexibility, the expandability and the reusability of the system are enhanced; 2, access to a database is carried out through an ADO technology, data automatically acquired in shield tunneling construction are read, access to the database is carried out through the ADO technology, connection with a database interface is carried out with an ODBC method, and an ADO is an object model based on an OLE DB, and comprises all data types capable of being described by an OLE DB standard interface; and 3, by means of a programming technology oriented to objects, multiple two-dimensional graphs such as curve charts, bar charts and pie charts are output.

Description

technical field [0001] The invention belongs to the technical field of subway track construction application, and in particular relates to a shield section risk management system based on shield machine construction. Background technique [0002] Shield / TBM tunnel construction technology has been widely used in my country's water conservancy and hydropower, railway, transportation, urban underground engineering, oil and gas pipelines, and national defense tunnel construction. The advantages and characteristics of the construction method are very obvious: the production process is relatively safe, the possibility of serious safety production accidents in the tunnel is small, the production process is relatively easy to control, the amount of ground movement and ground subsidence caused is small, and the control is relatively easy , especially its information-based production methods make it easier for us to realize information-based control and real-time management of the const...

AI Technical Summary

Problems solved by technology

[0003] (1) Each type of shield has its best scope of application, and it is impossible to adapt to any stratum. Once the selected shield type does not match the hydrological and geological conditions, there may be a big risk;

[0004] (2) The degree of mechanization and scientific and technological content of shield tunneling is relatively high, and it is difficult to replace and repair important parts during construction. Once a serious mechanical failure or component damage occurs in the shield tunneling process, it is quite difficult to repair (such as: Welding cutter head, replacing severely worn tools, etc.), and the maintenance process will also bring greater risks (such as: encountering unknown harmful gas when opening the warehouse and changing the tool, acetylene poisoning when repairing the welding cutter head);

[0005] (3) When the strata traversed by the shield tunnel are complex and changeable, and the underground environment is relatively complex (such as shield construction encounters bad strata, unknown underground obstacles, etc.), risks are likely to arise;

[0006] (4) The shield tunneling construction has a great relationship with the experience of the shield tunneling operator and the ability to operate the shield tunneling machine. Once the shield tunneling operator is inexperienced, the ability to control the shield tunneling tunnel is limited, or the operation is violated, the emergency (abnormal) If the situation lacks sufficient judgment ability, it is easy to cause greater risks in shield construction
